The invention discloses a centralized spot market clearing method. The method comprises the following steps: determining a network loss rate and a network loss distribution factor; calculating the total system network loss of the planned section according to the network loss rate; calculating to obtain a node network loss component according to the network loss distribution factor and the total system network loss; and establishing the spot market clearing optimization model considering the network loss estimation and the network loss distribution factor according to the node network loss component, and considering the network loss, so that the solving precision of the centralized spot market clearing result can be improved, and the safe operation level of a power grid is improved. 本发明公开了一种集中式现货市场出清方法，包括：确定网损率及网损分布因子；根据网损率计算计划断面的系统总网损；根据网损分布因子和系统总网损计算获得节点网损分量；根据节点网损分量建立考虑网损估计与网损分布因子的现货市场出清优化模型，本发明考虑了网损，能够提高集中式现货市场出清结果的求解精度,提升电网安全运行水平。
